Using "Subfiles in RPG IV" by Kevin Vandever, I am trying to enhance my programming skills. I have a program that uses multiple subfiles (side-by-side), and the second subfile has more records than the first. The first subfile shows the invoice information and the second subfile shows the distribution. There can be more than one distribution record to an invoice record. How can I control the cursor position to display the related data when toggling back and forth?
